Verdict
The clearest difference is ads: Kero at none against Trainline's shown. Kero also leads on monetization model (free vs free with in-app purchases) and iOS requirement (15.1 vs 17.0). Trainline's advantage is ratings volume (11K vs 1) and update cadence (weekly vs every 3 weeks). On price, rating, in-app purchases and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
On the App Store both sit at effectively the same score — 4.9 for Trainline against 5.0 for Kero. That said, the two scores are not equally well evidenced: Trainline has 11K ratings behind it against 1, so its average is the more settled of the two.
Trainline ships an update weekly, Kero every 3 weeks. The most recent releases landed on October 28, 2026 and October 12, 2026 respectively.
